Description

Technical Field

[0001] This utility model belongs to the field of embryo culture technology, specifically relating to an embryo cryopreservation carrier clamping device. Background Technology

[0002] Embryo freezing is a method in which embryos and freezing fluid are placed in cryotubes or cryocarriers, which serve as carriers for slow (for embryos on days 2-3) and rapid (for blastocysts on days 5-6) cooling to allow the embryos to become still and be preserved in liquid nitrogen at -196 degrees Celsius.

[0003] The patent, with publication number CN221670819U and titled "An Embryo Freezing Carrier Clamping Device," discloses a handle equipped with a pushing mechanism, a gripping mechanism, a connecting mechanism, and a device mechanism. The pushing mechanism includes a mounting groove at the top of the handle, within which a hydraulic cylinder is fixedly mounted. A round rod is fixedly mounted at the front end of the hydraulic cylinder. A door is fixedly mounted at the top of the handle, and a handle is fixedly mounted at the right end of the door. The device features a pushing mechanism that allows the output shaft of the hydraulic cylinder within the mounting groove to reciprocate, driving the clamp to grip the carrier. The hydraulic output gripping ensures even force distribution, safely and reliably gripping the frozen carrier, reducing unnecessary losses caused by uneven force leading to the carrier falling and being damaged.

[0004] However, the technical problem or defect is that the pushing mechanism is set inside the handle, and one end of it is connected to the gripping mechanism. During the extension and retraction of the gripping component in the gripping mechanism, a clamping working state with a slender structure is formed, which is inconvenient to use and not easy to store. Therefore, based on the above defects, the applicant has proposed a better technical solution to solve the above technical defects.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] like Figures 1 to 3As shown, an embryo freezing carrier clamping device includes an outer shell 1 with an internal cavity 11, a slider 2, a telescopic mechanism 3, an inner cylinder 4, and a clamping mechanism 5. The cavity 11 has sliding grooves 12 on opposite sides. The slider 2 is slidably connected to the sliding grooves 12 through a sliding piece 21 provided on it. The telescopic mechanism 3 is located at the top of the cavity 11 and is threadedly connected to the slider 2. The inner cylinder 4 is located at the lower end of the slider 2 and has a partition 6 inside to divide it into an upper chamber 41 and a lower chamber 42. The clamping mechanism 5 is located in the lower chamber 42.

[0030] This utility model regards the outer shell 1 as a container, and uses a clamping mechanism 5 set inside the outer shell 1. It can be driven by the telescopic mechanism 3 to extend out of the outer shell 1 to clamp and pick up the embryo freezing carrier rod. Alternatively, it can be stored inside the outer shell 1 by the telescopic mechanism 3. This can effectively shorten the overall length of the clamping device, making it easier to use and store, and improving the convenience and comfort during use.

[0031] In this embodiment, please refer to Figure 1 and Figure 2 The telescopic mechanism 3 includes a motor 31, a threaded rod 32, and a limiting protrusion 33. The motor 31 is located at the top of the cavity 11, and its output end is connected to the threaded rod 32. The end of the threaded rod 32 away from the motor 31 is provided with the limiting protrusion 33. The slider 2 has an internal thread that engages with the threaded rod 32. When the motor 31 rotates, the threaded rod 32 engages with the slider 2 to drive the slider 2 to slide up and down. The limiting protrusion 33 limits the displacement distance of the slider 2.

[0032] In specific operation, when the drive motor 31 rotates in the forward direction, it drives the threaded rod 32 to rotate. Through the threaded connection between the threaded rod 32 and the slider 2, and the cooperation between the sliding plate 21 and the sliding groove 12 on the slider 2, the slider 2 can be driven to slide downward. When the drive motor 31 rotates in the reverse direction, it drives the threaded rod 32 to rotate in the reverse direction, which drives the slider 2 to slide upward. Finally, by using the forward and reverse rotation of the drive motor 31, the slider 2 is driven to slide up and down along the inner wall of the cavity 11, thereby driving the inner cylinder 4 to slide up and down.

[0033] In this embodiment, please refer to Figure 1 and Figure 3 The clamping mechanism 5 includes a drive assembly 51 and a clamping assembly 52. ​​The drive assembly 51 includes a second motor 511, a rotating shaft 512, a first sprocket 513, a transmission chain 514, and a second sprocket 515. One end of the rotating shaft 512 is rotatably connected to the side wall of the lower chamber 42, and the other end is connected to the second motor 511. The second motor 511 is located on the side wall of the lower chamber 42. The first sprocket 513 is located on the rotating shaft 512, and the second sprocket 515 is located on the clamping assembly 52. ​​A transmission chain 514 is provided between the first sprocket 513 and the second sprocket 515.

[0034] Specifically, the clamping assembly 52 includes a double-ended screw 521, a clamping plate 522, and a guide rod 523. The double-ended screw 521 is rotatably connected to the lower chamber 42, and a clamping plate 522 is threadedly connected to both sides of it. The guide rod 523 is located above the double-ended screw 521 in the lower chamber 42, and the clamping plate 522 is slidably connected to the guide rod 523.

[0035] In specific operation, when the inner cylinder 4 is driven to slide out into the cavity 11, the second drive motor 511 rotates in the forward direction and drives the double-headed screw 521 to rotate by the connection between the first sprocket 513, the transmission chain 514 and the second sprocket 515. The two opposing clamping plates 522 can be moved to the center to clamp the freezing rod. Conversely, the second drive motor 511 rotates in the opposite direction to drive the two clamping plates 522 to move outward and release the clamping of the freezing rod.

[0036] In this embodiment, a cover 7 is provided below the double-ended screw 521, and a rectangular hole 71 is provided on the cover 7 for the clamping plate 522 to pass through; the cover 7 can effectively prevent external impurities from falling into the lower chamber 42.

[0037] In this example, a control system (not shown in the figure) is also integrated into the housing 1. Both motor 1 31 and motor 2 511 are electrically connected to the control system. A switch is provided outside the housing 1 to control the rotation of motor 1 31 and motor 2 511. Motor 1 31 and motor 2 511 are conventional devices on the market, and their connection with the control system is a conventional technical means, which will not be elaborated on here.

[0038] The working principle of this utility model:

[0039] This utility model provides an embryo freezing carrier clamping device. In specific use, when it is necessary to clamp the freezing carrier, the drive motor 31 rotates in the forward direction, which drives the threaded rod 32 to rotate. Through the threaded connection between the threaded rod 32 and the slider 2, and the cooperation between the slider 21 and the groove 12 on the slider 2, the slider 2 can be driven to slide downward, thereby driving the inner cylinder 4 to slide and causing the clamping assembly 52 to extend out of the outer shell 1.

[0040] Drive motor 2 511 rotates in the forward direction and drives double-headed screw 521 to rotate by the connection between sprocket 1 513, transmission chain 514 and sprocket 2 515. The two opposing clamping plates 522 can be moved to the center to clamp the freezing rod. Conversely, drive motor 2 511 rotates in the opposite direction to drive the two clamping plates 522 to move outward and release the clamping of the freezing rod.

[0041] When it is necessary to retract the clamping assembly 52 into the outer shell 1, the drive motor 31 rotates in the opposite direction, which in turn drives the threaded rod 32 to rotate in the opposite direction, thereby driving the slider 2 to slide upward, thereby causing the inner cylinder 4 to retract into the outer shell 1.

[0042] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
